Viega 28770 – Frequently Asked Questions
1) What size pipe does the Viega 28770 MegaPressG coupling connect?
The Viega 28770 MegaPressG coupling joins 2-1/2 inch to 2-1/2 inch, so it is a straight same-size coupling rather than a reducer. Both ends are press connections (P1 x P2), meaning it presses onto two runs of pipe with a pressing tool rather than threading or welding.
2) What does the "with stop" mean on the Viega 28770 MegaPress coupling?
A coupling with stop has an internal pipe stop, so each pipe end bottoms out at a fixed insertion depth in the center of the fitting. That sets the engagement for you on a new run. If you need to slide the coupling fully onto an existing line to close a repair gap, you want a coupling without stop instead, since the 28770 will not slide past its center ridge.
3) What part number do I order for the Viega 2-1/2 inch MegaPressG coupling with stop?
Order Viega part 28770. That is the MegaPressG carbon steel coupling with stop, 2-1/2 inch by 2-1/2 inch. The G designation is the gas-rated version of the MegaPress line, so specify 28770 rather than a standard MegaPress number if the drawing calls for MegaPressG.
4) Is the Viega 28770 coupling made of carbon steel or stainless?
Carbon steel. The 28770 MegaPressG coupling is a carbon steel body, so it is intended for use on carbon steel pipe systems, not for potable water copper or PEX lines. It is made in Germany.
5) What is Smart Connect on this Viega MegaPressG fitting?
Smart Connect is Viega's unpressed-connection feature built into the 28770 coupling. An unpressed fitting leaks visibly during system testing so it can be found and pressed before the job is closed up. It is a verification aid, not a substitute for pressing every joint.
6) Do I need to order anything else with the Viega 28770 coupling?
The coupling is the fitting only. You supply the 2-1/2 inch carbon steel pipe, the press tool with the correct 2-1/2 inch jaw or ring set, and any pipe support. The sealing element is integral to the fitting, so there is no separate gasket to buy for it.
